There is HOPE for you and your dog! 
Christina's Trademarked
Total Harmony Dog Transformation® System

For 20 years, I have dedicated myself to preventing dogs from being given up due to behavior problems that could have been effectively treated, keeping dogs safe and happy together with their owners for life!

A recognized Dog Expert nationally and internationally and acclaimed dog trainer and dog behaviorist, I specialize in rehabilitating and effectively treating dogs with behavior problems caused by aggression, fear or both.


Obedience training fails behavior problems because the dog is too aggressive, fearful or both to be able to do them and correction based training worsens them.

What makes us different makes all the difference! (TM)

Having a dog with a Behavior Problem(s) - Aggression, Fear, Both or in need of Rehabilitationcan be extremely stressful, and can also create serious real-life problems. In addition to watching the dog you love and care for suffering, you are suffering as well. For 20 years, I have immersed myself continually in education and experience obtaining unique skill with the most problematic, complex and challenging dogs that had been given up on.

I fully understand the urgency in providing successful treatment and permanent Behavior Problem elimination as quickly as possible and so we reach far beyond the norm:

Direct, hands on, in and out Home Treatment - 

at no additional charge.

Where your dog's behavior

problems are actually

created and happening, not within an artificial re-creation in a facility and never virtually, cannot train or treat a dog with behavior problems by describing to you - we agree with the American Kennel Club. Further, we take on the travel time, cost and effort to travel

to your specific location. 

My Total Harmony Dog Transformation® System

Blue- Siberian Husky
Fear on Walks, Separation Anxiety

"Christina literally saved our dog (and us!)"

Blue Siberian Husky NY Clever K9 Great Review

"Since moving to NYC, our dog Blue became very frightened and skittish on walks but worse she soon became very anxious when left alone, something that had never happened before. She would completely panic, circling us when we tried to leave and barking non stop when we were gone. This became a huge problem as several neighbors complained and we got a warning from the Board and were new to the building. We tried a trainer who put a citronella collar on her which she just barked through and told us to crate her - she injured her mouth (a vet trip) trying to chew through the crate. As we couldn't move again we became desperate as to how to keep Blue, who we love dearly. A coworker recommended NY Clever K9 and Christina Shusterich, (the owner) who immediately started working on both problems, making changes almost as soon as she walked in - no crate! It seems miraculous but with sessions and our practice we can now leave Blue alone and she is so much calmer on walks - she even likes them now! Christina is not only intelligent but very compassionate, quickly acting as a mediator with our landlord to give us time to work with Blue, Christina loved Blue and was very kind and patient with us as we were extremely stressed. We really can't thank her enough!"

Percy - Batman/ Dachshund 
Aggression to handling

"Christina is a gifted behaviorist,
we are deeply grateful"

Percy - Dachshund  Aggression to handling NY Clever K9 rave review

"Christina is a gifted behaviorist. She is highly skilled at understanding and interpreting dog behavior and designing personalized and creative solutions for canine behavioral issues that often cause dog owners to give up on their animals. Christina worked patiently and persistently with me and my family to help us understand the source of our dog's biting (pain, leading him to respond in aggression) and to circumvent triggers that traditionally would cause the dog anxiety and frustration. We are deeply grateful for the compassionate care and wisdom she so generously shared with us and the lessons we learned. The only one more grateful is our Percy!"

Juniper - Pomeranian
Fear aggression to touch, leash aggression, anxiety/rehabilitation, fear of noises/
tight spots

"Spent a lot of time researching trainers
and schools,
highly recommend Christina!"


Juniper - Pomeranian Aggression & Fear Positive Review NY Clever K9

"I spent a lot of time researching dog trainers and training schools in New York before choosing Christina, and I know I made the right choice. My newly adopted rescue dog Juniper was having trouble adjusting to the city. He was extremely leash-aggressive--he barked and lunged at other dogs, garbage trucks, and any other loud sounds. Additionally, we had an issue with my neighbor across the hall, whose dog had attacked Juniper soon after we arrived. Just trying to get Juniper out the door for a walk was difficult, as the smell of the other dog made him snarl, bark, growl as we tried to walk past it. Worst of all, Juniper's anxiety, along with possible issues from his past, meant that he was often lashing out at me, snapping and growling if I approached him the wrong way.

Today we went for a 90 minute walk in Central Park. Since it was warm and sunny for February, the park was crowded with people, bikes and dogs. Juniper did not bark or lunge once the entire time, and even was able to interact a few times with other dogs. Narrow pathways where we couldn't avoid some dogs weren't a problem, because now, thanks to Christina, I have a plan to help deal with Juniper's anxiety around other dogs in tight spaces. He is no longer nervous about being touched, so we stopped to have some cuddle breaks. A woman passing by called Juniper a "good little dog."

Christina taught me how to understand Juniper's body language, how to deal with difficult situations around other dogs, and even how to make my apartment a place where he can feel safer and more secure. We worked out a method that allows us to walk quietly past my neighbor's apartment without setting off her dog. I really appreciate Christina's time and patience with both Juniper and me. It wasn't always easy, but I feel like we are on a path towards success, and that life will get better and better for Juniper.
I highly recommend working with Christina!" ~ Kirsten Anderson

such an impact for good as
Christina Shusterich of
NY Clever K9."

NY Clever K9 Christina great Shelter Dogs Reviews

"Christina is both a behavior specialist and trainer and her insight into the dogs is exceeded only by her dedication to them. Christina has been working tirelessly with our dogs.


Before Christina joined our group, one third to one half of our dogs were returned due to behavior problems. Since Christina has been working with our group only one dog has been returned and has since been placed in a more appropriate home."
